HOSE-COUPLlNGr SPECIFICATION. forming part of Letters Patent 530.322,286, dated July 14, 1885 Application filed May 5, 1885 (No modell)fication, reference being had therein to the accompanying drawings.

My inventionrelates to improvements in hose-couplings, the object ofwhich is to provide a safe and reliable couplingwhich can be readilyattached and detached, while at; the

same time it cannot be detached by jar'sior shocks or by longitudinalthrusts or pressures. Referring to the drawings, Figure 1 is a side viewof a faucet having the male portion-of my improved coupling formedthereon. Fig. 2 is a side view of the female portion of my coupling.Fig; 3 is a side view, of the male portion'ofmy coupling as applied to ahose connection. Figs. 4 and 5 are sectional views of the devices shownin Figs. 2 and 3 and the Fig. 6 is .an end view of the female portion ofthe coupling. Fig. 71s] 5 fastening device.

an end view of the male portion. Fig. 8'is a longitudinal sectional viewof the male portion,

in which is inserted apaclging-ring. Fig. 9 is a side elevation of ahydrant-having the male portion of the coupling att-a'ehed theretoprovided with a latch. Fig-. 10 is a side eleva-' tion of the femaleportion of the coupling having the recess'to receive the latch shown inFig. 9. Figs. 11 and 12 are end views of the male and female portions ofthe couplings shown in Figs. 9 and 10. Figs. 13 and 14. are sectionalvews of the male andfemale portions, showing a bolt adapted to be slidback and forth to lock the sections together.

A indicates the main body 13, for the passage of the iquid. The

front end of the section A J in diameter than the rear portion, asindicated at O, and is ground down, as shown-at D, to snugly fit in theground recess E, formed in the female section F, thus forminga tightjoint. The section A is provided with an enlarged annular portion, G,against which the enlarged end of the section F abuts, said annularportion G being provided with an enlarged porfully appear hereinafter.

- held forward by which can be regulated by the set-screw R.

the section F is pro- -come together, or it may be,

or section of the the spigot,V, for beer-tanks and hydrant-con maleportion of the coupling,hav'ng a central ti )n or projection, H, havinga cavity, I, to rcceive a spring-operated bolt, K, seated in the sectionF of the coupling. The section A is also provided ,with lugs L,adaptedto fitin recesses formed in the section F, as will more ling end of thesection F is also provided with an enlarged annular portion, as shown atM,

and, as before stated, is ground down true on its inner surface toreceive the ground end D The inner or coup-- of the section A, theenlarged portion M being provided with a projectio n,N,cor1esponding tothe projection H on the section A.

' The projection N is provided with an aperture, O, to receive-the boltK, said bolt being the spring 1?, the tension of Thee'nlarged end ofvided with longitudinal slots or openings S, which terminate intransverse slots T. The outer edges are made tapering orwedgeshaped, asshown at a;

When it is desired to couple the sections to- 'gether, the end of.section A is inserted in the ,endof section F, the lugs L entering theslots S, and when the sections are thus squarelybrought into positionthe sections are turned partially in reverse direction, to bring thelugs into the transverse slots T, the inclined sides of which tend todraw the sections more closely together,.and when the parts have beenturned to the proper position the end of the bolt K will be thrownforward into engagement with the recess 1, and thus prevent thepartsfrom becoming detached.

Inmany instances it is not convenient or. even possible to have thetheywere made or. ground tomatch each other as in the case of nections, thatthe section F will not form a perfect joint with said spigot; and'inorder to secure a perfectly-tight joint at all times I b, in the endandflthicker at the rear end than it is at the same sections as frontend, so that when the ends of. the section are brought togetherthepacking-ring will yield to the pressure, permitting the-operator tocouplcthe parts together, while the pressure of the packing-ring on thesides of the ('avityE will prevent the escape of liquids, and thus forma tight joint.

For hydrantconnections, 850., the spigot shown in 1 will prove veryeffective and.

convenient, not only on account of the facility with which the hosecanbe attached and detached, but the projection H will serve as asupport for buckets and other "essels having bails; and in suchconnections as the one just referred to I may dispense with thelockingbolt K and substitute therefor a latch pivoted in a slot orrecess formed in the projection H and adapt the latch to rest in arecess formed in the projection N. This form of lock or fastening willprevent the parts from being turned, and thus hold the sections firmlytogether.

Having thus described my invention, what I claim, and desire to secureby Letters latcut, is-- 1. A hose-coupling consisting of two sections,one section being ground tapering or cone shaped at its end and providedwith lugs to fit a seat correspondingly ground and engage with recessesformed in the other section, said tapering or cone-shaped end beingprovided with an annular groove to receive a packing-ring which isconcave 011 its inner side and convex on its outside, in combinationwith a suitable catch for holding the sections from lateraldisplacement.

2. In a hose-coupling, a rubber packingring having its inside concaveand its outside convex,and adapted to fit in an annular groove or recessformed in the tapering or cone-shaped end of the male portion of thecoupling, as setforth. y

In testimony whereof I affix my signature in presence of two witnesses.
